Notes:

Central Brisbane River and Stanley River WSS supplemented allocation diversions were not available from Queensland Department of Environment and Resource Management's (DERM's) Water Management System (WMS) at the time of publication. These have ben reported as (–) in the 2011 Account.

b. Non-urban surface water allocation remaining – reconciliation

The following table shows the non-urban surface water allocation reconciliation. Due to the very wet year, demand was lower than in previous years and combined with the 100% allocation announcements, this has resulted in a higher forfeiture of surface water allocation.

Method

Supplemented allocation diversions were provided by DERM from the WMS database for each water resource plan area. The current resource operation plan reporting requirements do not allow for reporting by 'type' of use. This line item was calculated by removing the urban diversions (line item 17.12 Surface water allocation diversion – urban water system) from the total supplemented allocation diversion. This represents the remaining high-priority holders and all medium-priority holder diversions.
